This is not accurate.
see http://www.fueleconomy.gov/feg/ratingsNewSticker.shtml
for info on sticker. That site also shows the test routine used to derive the EPA estimates. They changed the testing scheme about 5 yrs ago and included some very agressive driving techniques to more accurately reflect how "normal" driving consumes fuel. This is why the European fuel economy estimates are so wildly different than the ones used over here. IMO the Euro numbers are "hyper miler" driving and not at all realistic.

The good news is that you can easily beat these new EPA estimates if you try.
